Use Stella

I waited a bit until everyone in the classroom was gone. Stella must have realized my intentions, because while everyone else was leaving, she hoped on to the teacher's desk, layed back and spread her legs. I didn't need much of an invitation after this. The moment everyone was gone, I unzipped my pants and penetrated her ass, without any sort of warning.

"Aaaahhhhh!!!!"

I knew from last time that she didn't deserve any mercy. I would have her begging for more until I can't give it any longer. Her screams were louder than last time too. A bunch of times some group of girls walked in to investigate the commotion, only to run away blushing. When I had enough, I pulled out and painted her with my seed. Once again, she left me satisfied, and I left her panting with my cum on her.
